Yes i heard one aria. It is amazing. Tschaikowskis instrumentation is ingenious and the music heart moving.
I totally have the same feeling. His "trara, tschingarasabum"-music with cymbals..... i really don't like, it is kinda superficcial and only on effect.I have only heard the waltz from Eugin Onegin. BUt I like that one a lot. I have very mixed feelings about Tchaikovsky. SOme of his music I strongly dislike, and some of it I love passionately!
